It comes as a separatist leader in eastern Ukraine says his region wants to hold a vote on joining Russia. Biden warns Putin not to go “an inch” of NATO territory – the last for Ukraine Key developments: • This woman is fighting her own battle against Putin – and all she needs is her cell phone • Responding to sanctions, Putin is trying to wield his own financial sword • Strong explosions on the outskirts of Lviv in Western Ukraine • Kremlin summit Military officials make their first appearance in weeks after “significant” silence • Theater bombing survivor speaks of chaos in besieged Mariupol Leonid Pasechnik, the leader of the self-proclaimed People’s Republic of Luhansk, said he could hold a referendum “in the near future” to ask voters if they support the region becoming part of Russia. Russia has supported separatist insurgents in the region, and near Donetsk, since an uprising broke out there in 2014 following the annexation of Crimea. Following a recent briefing by the UK Department of Defense, which said the battlefield in northern Ukraine remained “largely static”, Russian troops were focusing their efforts on “encircling” Ukrainian forces in the east. The Foreign Ministry said local counterattacks had hampered Russia’s efforts to reorganize its forces. There are fears that Chernihiv, in the north, could become the next Mariupol, with 44 seriously injured – including three children – unable to be evacuated for treatment, the city mayor said. The city has been cut off by Russian forces. Lviv, to the west, has also come under fire, with Putin’s forces hitting a fuel depot with high-precision cruise missiles. Meanwhile, two humanitarian corridors have been agreed for Sunday, according to the Deputy Prime Minister of Ukraine. Minister Iryna Vereshchuk said the corridors, which are used to evacuate civilians from the front line areas, will extend from the Luhansk and Donetsk regions and will include people leaving Mariupol in private cars.

Nadhim Zahawi told Sophy Ridge on Sunday that “the Russian military has miscalculated” its invasion of Ukraine. “Ukrainians have fought like lions,” he said. “They defended their country. They believe in their freedom.” Regarding a possible peace agreement between Ukraine and Russia, he said that any serious peace agreement should be negotiated “face to face between Presidents Zelensky and Putin.” Putin “can not stay in power” The United States has no strategy for regime change in Russia, Secretary of State John Kerry has said, adding that Russian President Vladimir Putin “can not stay in power.” “I think the president, the White House, pointed out last night that, quite simply, President Putin can not have the power to wage war or attack Ukraine or anyone else,” Blinken said during a visit to Jerusalem. “As you know, and as you have heard us say over and over again, we do not have a regime change strategy in Russia – or anywhere else – on this issue.” In a powerful speech in Warsaw, Poland, the US president relied on previous statements in which he called Vladimir Putin a “butcher”, describing him as a “dictator” and saying that ending the war in Ukraine was “the task of our time”. .
